Abstract
Signal wavelength in an optical transmission system is optimally set. Before operation of the system is started, the intensity of a particular frequency component is measured by a dispersion monitor while sweeping the wavelength of a tunable light source over a wide range, to determine an optimum wavelength. Once operation of the system is started, the wavelength is swept over a narrower range containing the optimum wavelength, and the optimum wavelength is updated with a wavelength determined based on the result of the sweeping.
